HERMANN ALBERT Rosana: nnxnn, or,V HAMBURG, GERMANY, AssIGNoB. To lermi-y BAU--GESELLSCHAFT n. B.' H., or MUNICH, GERMANY, A oonronA'rIoN or Gna- My invention relates to chamber ovens in l which gas is produced from coal or other niaterial, andhas-for its object to se heat the walls ofthe indiyidual gasifying chambers as to avoidv an excessive heating of the gases gathering at the top or root" ot' the chamben together with the depositionA of graphite winch would result from such excessive heating. .l u

Inf-the aceompanylng drawingv I have shown the use of .my invention in conneetion with an oren having inclined chambers, but l desire it. to heunderstood that the Jinvention is' also applicable to'chainhers having a diti'erent arrangen'ient.

Figure 1 is a vertical ysection"through one ut' the gasit'ying chambers; Fig. 2 is a Vertical section taken through the l1eating`cl1annels at one Vside of a gasii'ying chamber, and Fig. if is a ("rosss'ectionon line 3--3 of Fig. 2.

The 'oren shown in the drawings comprises a .gas generator 1 from which pass upward through a channel 2, chamber '3 and duct l, to the vertical channels in which they become mixed with the heated airrising l from the channel 6 ofl the 'regenerator 7.v

(.omlms'tiun thustakesplace in the channels which. are arranged. vat yeach side .of each f gasitying chamber 8- (sce especially Fig. 3).

i Iu-l 't'ront of each channel 5 l provide an addiiional yertical channel 9, .separated from the corresponding channel/ .7 by a partition 10 having" perforatons 1.1'at. different levels. r|`he 'channels i) co'n'imunicate With the airsupply' channel v(l and-feed additional airdifferent levels, to the heatinggases rising" in the channels 5; From .the channels 5 longitudinal channels 14 conduct the heating gases, along thev side walls of the chambers 8.

of each' group of channels 14, and the upper channels 111, which communicate with the 'said horizontal channel 1.5, may be cut off lpartly or entirely h i l nieans ofa slide or damper 1G which'a ects all ot said upper channels equally. The'gases from the lower channels llllfirst'travel upward in a'passage `along a ypartition 19 and then downward through a channel V17 on the opposite side ot the partition tol the 'cross channel 18 connected Wit-h the'stack or other outlet. The partition`19 is perforated in line with the discharge ends of the lewe/r channels, toreceive slides or dam-pers 20 by which these lower channels may be cutoffor closed indiv Vidually. Each slide 20 is perforated so that vwhen it closes the respective channel 14 the gases from lthe other lower channels 14 may have annnobstruetedpassage to the channels 17 and "18.- The partition 19-serves to equalize the draft, which otherwise would he stronger" for'the lower-channels 14 than for the upper ones. The slides 1.6 and QO'are operated .from the. end of the oven :1t-Which the cliarnbers. areehargedpand are there- `forereadily accessible.

'Sight channels 21 may be proyided in line with the several channels-14, saidchannels 21 being normally closed by plugs 21" made of firebriek or othersuitable'material. Upon removing these plugs, the channels 14 may *be ,inspected duringV the operation of the OVER.

' It is advisable to make the chambers 8 narrower at the end toward which the heating .gases Howlin the channels 14, since-the heat naturally decreases as the gases approach the outlet, and withV the arf-rangement shownj (Fig. 3) the crpss section of the chamber 8- (and of the coal or other material therein) is greatest at the lower end of the chamber and decreases lgradually toward 'the upper end, corresponding-to the decrease in the temperature of the heating 'ga-ses. A better utilization of the heat is thus obtained. Figs. 1 and 2 also show outlet pipes 22 and 23 connected With a liquid receptacle 211 and a tar collector 25,but'thisarrangementy was not invented-'by me.
